When will the clouds turn into rain?

In life, we will always encounter a rain at one time or another. Sometimes, it seems that rain will not come but soon a sudden downpour caused us to get wet.

A few minutes earlier, all the raindrops would be in a faraway cloud, so why did they choose the exact moment of falling?

Yes, there must be a critical point, somewhere when the mysterious rains are still floating in the cloud, then they are too heavy to stay and decide to fall to the ground.

The rain is a bit more complicated than what we already know.

According to ScienceABC, it is time when small raindrops concentrate and bind to a point where their mass is affected by gravity. However, the rains are a bit more complicated than what we already know .

How do clouds form?

Clouds form due to water evaporating from the ground. On a warm day and the sun shines down on the lake all afternoon, the water in the lake will rise in temperature, eventually converting into a gas state and evaporating into the atmosphere. However, at this point in the process, rain is still in the form of tiny droplets that we cannot see.

Billions and trillions of tiny steam molecules like this fly up into the sky, they form floating clouds. The droplets formed clouds that looked rather heavy, but the clouds were not dense; in fact, the volume of air in the clouds is more than 1,000 times the volume of all these micro droplets.

The process of rain formation.

The warmer the air is, the more steam the vapor evaporates. But the higher the air, the colder the surrounding air makes the steam return to liquid form. Cold air cannot hold as much steam as warm air, and similarly, under lower air pressure, there will be less water vapor retained by the air. Therefore, a phase transition occurs. However, newly formed droplets are very small, 4-5 times smaller than the thickness of a sheet.

It is much easier for water to condense on certain particles, rather than naturally forming in the air. So if there is a large amount of dust or other particles in the air, the clouds will form much easier. Variations in topography, atmospheric interaction, temperature and wind can affect the type of clouds that are formed, but the basic process is the same.

Warm air rises below large areas full of steam strong enough to support clouds, which is why they "float" with all the rain contained there. This may seem contrary to all knowledge learned about gravity, but you need to consider how tiny these tiny droplets are really and you will understand, they float in the same way. which dust particles are making to constantly challenge the gravity of the Earth.

Slow down and grow

It takes about a million drops of super small steam like this to form a medium-sized raindrop.

When molecules become colder, they tend to slow down, instead of jumping over each other or flying with the air, these micro-droplets start to collide and stick together. You may not believe it, but you need about a million drops of super small steam like this to form a medium-sized raindrop. Groups of hundreds or thousands of tiny droplets continue to combine and grow until a mass can be affected by gravity and fall through the air that is supporting from below.

Strangely, large droplets struggle to connect with micro droplets, due to the powerful shift of air around these interactions. In such cold conditions in the upper atmosphere, ice crystals often form and act as an excellent catalyst for larger raindrops. Micro-droplets always attract ice crystals strangely, and can increase their weight very quickly. This sounds like it will lead to snow or hail. But no, in the process of falling back to earth, ice crystals will often return to the liquid state - also known as rain.

Does this world need rain?

In fact, microscopic steam can exist in a gas state down to -40 degrees (both F and C).

Although many people complain about the problem of airborne particles, as well as excessive dust in certain areas, but without them present in the upper atmosphere, it will never rain, and very quickly, this planet will become dry.

On a small scale, steam has no freezing point like in our large-scale tangible measurements. In fact, microscopic steam can exist in a gas state down to -40 degrees (both F and C). This threshold is quite cold, and usually only occurs at higher altitudes than where clouds form. Fortunately, thanks to our airborne particles and dust, these ice crystals and larger water droplets can form at higher temperatures (for example, -10 degrees Celsius).

So next time you see a truck that makes a lot of dust flying into the air, don't be upset. As you just know, this helps ensure that we continue to receive cool rains that bring life to the Earth from above.
